We really would like to understand why these fail and mitigate if possible.

Have you reported this upstream?

This phrase is a little eh weird. Could you rephrase to something like 
"Mypy checks type annotations..." or "Mypy is a ..."?

The LICENSE file contains this: "Portions of mypy are licensed under 
different licenses.  The files under stdlib-samples are licensed under 
the PSF 2 License, reproduced below."

Could you update the patch when you get an answer from upstream?

Thanks for the patch. :)
